3 Description

The TPS7C84-Q1 is a wide input, low-dropout regulator (LDO) supporting a 2.1V to 40V input voltage range and up to 150mA of load current. The TPS7C84-Q1 has both fixed and adjustable output types. Fixed output options include 3.3V and 5V. The output is able to be set between 1.2V and 39V with the adjustable device.

This device has a power-good (PG) output that monitors the voltage at the feedback pin to indicate the status of the output voltage. The EN input and PG output sequence multiple power supplies in the system.

The TPS7C84-Q1 is designed for up to 40V VIN battery-connected applications. The wide output voltage range allows the device to generate the bias voltage for silicon carbide (SiC) gate drivers and microphones as well as power MCUs and processors.

The device is available in both an SOIC package and a small VSON package with wettable flanks that facilitates a compact printed circuit board (PCB) design. The low thermal resistance enables sustained operation despite significant dissipation across the device.
